How can autumn cucumbers be highly yielding, and what month are autumn cucumbers suitable for planti

On the basis of fertile soil, it is necessary to understand the characteristics of cucumber fertilizer, combined with the erosion of pests and diseases, you can get a bumper harvest.

Cucumber is a shallow-rooted crop that requires a large amount of fertilizer. Producing 1,000 kilograms of commercial cucumbers requires kilograms of nitrogen, phosphorus, and potassium. The absorption of these nutrients by cucumbers varies depending on the growth period.

The growth period accounts for about one-third of the whole growth period, but the absorption of nitrogen, phosphorus and potassium only accounts for the total absorption5%, although the absorption at this stage is small, it has a great impact on plant development and flower bud differentiation; At the fruiting stage, the absorption rate of the three elements increased, and the maximum value could be reached at the full melon stage, with nitrogen uptake, phosphorus uptake accounting for 47%, and potassium uptake accounting for 48%. The absorption of the three elements decreased in the later stage of melon formation.

According to these tips, the fruit of water and fertilizer (including foliar fertilizer) and the degree of soil moisture can be obtained a good harvest.

First, cucumbers should be planted on ridges as much as possible. By ridge planting, the soil will be more permeable, and the soil will be softer, which is conducive to the growth of cucumber roots. Because cucumbers are shallow root crops, we can plant them by raising ridges and keeping the ridge height at about 15 meters.

The second point is when the cucumber is planted. Plant as shallowly as possible. Because many cucumber seedlings are now grafted, when the melon seedlings are planted deeply, the grafting position will be buried deep in the soil, and it is easy to send out new roots from the grafting part, in which case the grafting will lose its meaning.

After the melon seedlings are planted too deeply, it is easy to cause the base of the cucumber stem to be infected with pathogens, increase the probability of cucumber infection, and virtually increase our control costs.

The third point is a problem that many of our growers are prone to make, that is, the cultivation of melon seedlings is crooked. What are the consequences of planting seedlings untidyly? When we tie vines, it is easy to sprain the base of the cucumber, resulting in the phenomenon of cucumber wilting and dead seedlings.

The fourth point is one that we growers need to pay attention to. After the cucumber is planted, the side buds appear, and many growers will worry that it will consume too many nutrients, so they immediately pinch off the side buds. Because the side buds target the growth of the underground root system, breaking the side buds too early will affect the growth of capillary roots.

We are advised to grow after the side buds have grown to 10-15 cm. , and then pinch off these side buds, which is conducive to promoting rooting and strong seedlings, and is more conducive to the high yield of cucumbers in our later stage.

Autumn cucumbers have the advantage of high production and short growth period, but many farmers do not know how long they are planted. The most suitable planting time for autumn cucumber is in July and August, not only to choose the appropriate sowing time, but also to manage the autumn cucumber in the middle and late stages. Mid-to-late management methods and common problems of autumn cucumbers:

When the cucumber seedlings have grown to 2-3 leaves, they can be planted. Autumn cucumber planting is best chosen at dusk or in the afternoon on a rainy day, after all, the temperature is high during this process. After planting, water a certain root.

Generally, it is necessary to use dilution to obtain human urine feces, and then add an appropriate amount of urea solution to carry out watering. In this way, not only watering, but also applying seedling fertilizer, is very beneficial to the growth of cucumber seedlings. In addition, remember to re-water the cucumber seedlings the next morning after transplanting.

Cucumbers in different periods of water demand is also different, cucumber germination period water consumption, always keep the soil layer moist, do not water too much, otherwise it is very easy to cause its root rot. However, in the seedling and early flowering stages, it is only necessary to maintain the moisture content of the soil layer at around 80% to understand how to effectively regulate the moisture content. If you water too much during this period, it is very easy to cause cucumber seedlings to grow vigorously or to root up.

But during the fruiting period of cucumbers, the amount of water used is particularly large. Reproductive growth and vegetative growth occur at the same time during this period, so be sure to hydrate and moisturize on time. However, in the case of watering cucumber seedlings, you should also remember to water frequently with small water, not flood with large water.

For the top dressing level, in addition to the application of foot fertilizer, effective fertilization is also required at the end of the stage. Cucumber has a large demand for three elements of light fertilizer, in which zinc is larger, followed by nitrogen, and then phosphorus, so both base fertilizer and fertilization need to be dominated by these three elements. Because the rhizome of cucumber is very shallow, its fertilizer tolerance at the seedling stage is also weak, if the bottom fertilizer is very sufficient, it can be less fertilizer or no fertilizer.

If you want to apply fertilizer, you should also choose thin fertilizer as much as possible, and the key is to take basal fertilizer as the dominant one.

When the young plant grows to 10cm high, it needs to be fertilized gradually, generally 15-20 kg of three-element compound fertilizer for 1 mu of drought-tolerant topdressing. But in the cucumber sitting period, you can also top dressing again, light fertilizer three-element compound fertilizer 25-30 catties. In the back, it is proposed to top dressing once after every 2 pickings to ensure the requirements of organic fertilizer for cucumbers.

At the same time, in order to increase the production of cucumbers, it is also necessary to spray carbohydrate compound trace element fertilizer or multi-element compound trace element fertilizer immediately after the cucumber setting period, which can not only increase the production of cucumber, but also reduce the risk of disease and improve the quality of cucumber.

It can be planted in July and August, so you must water it in time, ensure the moisture of the soil, and pay attention to the fertility of the soil.

Autumn cucumber is more suitable for planting in September, so that the management can be high-yielding, first: cultivate strong seedlings, second: scientific transplanting at the appropriate time, third: field management.

Autumn cucumbers are more suitable for planting in September. From the perspective of the temperature required by cucumbers, cucumbers are temperature-loving vegetables, which are temperature-loving and cold-tolerant. The suitable temperature for growth is 20-25 degrees.

The maximum temperature is generally about 35 degrees Celsius, and when the temperature reaches 38 degrees Celsius or more, the root system stops growing, and root rot or death occurs. Therefore, the growth of autumn cucumbers can be arranged in a suitable growth temperature environment in order to achieve high quality and high yield. There is a difference between the north and the south of 20 25 degrees, and the approximate time in the Huanghuai region is in September, which requires seedlings to be raised in early August, so that the fruiting period catches up with the large temperature difference between day and night in September, in order to benefit the fruit and improve the quality.
